聚酯产业链月度报告：反内卷叙事提振，价格开始回暖-20251031

Report Industry Investment Rating No relevant content provided. Core Viewpoints - Global crude oil supply is expected to be loose with an increasing surplus, while demand will gradually recover from November to December. The Fed's interest rate cuts may boost demand [10][33][36]. - In the polyester industry chain, anti - involution may lead to an active contraction of the supply side. Although demand was better than expected in October, there is still a risk of a lagging decline. The low - profit situation of PTA and bottle chips may improve [10][112][113]. Summary by Directory 1. Polyester Industry Chain Market Review - PX: The 200 - million - ton/year PX plant of Zhejiang Petrochemical's maintenance plan was not fulfilled. The monthly average operating rate in October increased slightly, and the inventory increased slightly. The consumption was still good in October. The price was mainly affected by crude oil, first falling and then rebounding [17][19]. - PTA: In late October, Dushan Energy's 270 - million - ton/year new PTA plant was put into production. The monthly average operating rate increased slightly, and the social inventory continued to decline. The spot processing fee was very poor, falling below 100 yuan/ton [20][21]. - MEG: Shandong Yulong Petrochemical's 80 - million - ton/year ethylene glycol plant was put into production in October. The comprehensive operating rate reached a new high this year, and the port inventory increased. The price performance was relatively weak [24]. - Short Fiber: The operating rate decreased slightly in late October. The demand was expected to remain weak, and the spot processing fee was generally acceptable. The price first fell and then rebounded, with a slight cumulative decline [27][29]. - Bottle Chips: The operating rate rebounded from a low level and then stabilized in October. The domestic demand decreased month - on - month, and the export declined from August to September. The spot processing fee fluctuated little, and the price increased slightly cumulatively [31]. 2. OPEC+ Continues to Increase Crude Oil Production - Supply Surplus Expectation Intensifies: In October, eight OPEC member countries decided to increase production by 137,000 barrels per day in November, with a cumulative increase of 2.74 million barrels per day. EIA continuously raised the global crude oil production forecast, and the supply surplus expectation intensified. Although the demand decreased seasonally, with the impact of the Fed's interest rate cut and other factors, the international crude oil price rebounded after a decline, with a small cumulative decline [33]. - Demand Will Seasonally Recover: The Fed's interest rate cuts may boost demand. The process of the seasonal decline in crude oil demand has basically been completed, and it will gradually recover from November to December [39][48]. 3. The Anti - Involution Narrative Resurfaces - PTA New Plant Commissioning: In October, Dushan Energy's 270 - million - ton/year new PTA plant was put into production. The PTA processing fee was extremely low, which attracted the attention of the competent department. Anti - involution may lead to an active contraction of the supply side [51][63]. - Ethylene Glycol Supply Tends to Be Loose: The ethylene glycol operating rate remained at a high level in October, and the supply tended to be loose. The profit of coal - based ethylene glycol declined continuously from August to October [64][68]. 4. Demand Is Better Than Expected but Still at Risk of Decline - Polyester Operating Rate Rises Steadily: In October, the polyester and loom operating rates increased slightly, showing the characteristic of "no off - season in the off - season". From January to September, the growth of polyester production mainly came from bottle chips, which drove the increase in the consumption of PTA and ethylene glycol [71][75]. - PTA De - stocks and Ethylene Glycol Accumulates Stocks: PTA social inventory continued to decline in October, while ethylene glycol port inventory increased. There is a risk of inventory accumulation due to the expected decline in demand [76][80]. - Polyester Profits Are Still Under Pressure: In October, polyester profits first increased and then decreased. The spot processing fee of short fibers was at a relatively high level, and the profit of bottle chips was expected to improve [81][83]. - Stable Export of Filament and Gradual Recovery of Bottle Chip Export: From January to September, the exports of filament, bottle chips, and short fibers increased year - on - year. The export of bottle chips had the largest scale and increment, but there was a large pressure of year - on - year decline in single - month exports in the later stage [86][89]. - Risk of Lagging Decline in Demand: Although the demand in October was better than expected, there is still a risk of a lagging decline. The operating rates of pure polyester yarn and Jiangsu - Zhejiang looms are expected to decline in the later stage [95][98]. 5. Domestic Demand for Textile and Apparel Improves Month - on - Month, but Exports Face Downward Pressure - Domestic Demand for Textile and Apparel Improves Gradually: In 2025, the growth rate of domestic consumption of textile and apparel was not high, but it improved month - on - month. The peak season is mainly in the second half of the year, and attention should be paid to the consumption situation in the fourth quarter [104][105]. - Textile and Apparel Exports May Recover from a Low Level: From January to September, the cumulative export of textile and apparel decreased year - on - year. In October, Sino - US trade relations are expected to ease, which is conducive to the recovery of textile and apparel exports [108][109]. 6. Summary and Outlook - Summary: In October, OPEC+ continued to increase production, and the international crude oil price first fell and then rebounded. The prices of polyester industry chain products also showed a similar trend, with better performance than crude oil. The supply and demand of the polyester industry chain increased in October, but the profits were still not ideal [110][112]. - Outlook: From November to December, the international crude oil market has both positive and negative factors. The supply of the polyester industry chain is expected to contract along with the decline in demand. The profits of upstream and mid - stream products such as PX, PTA, and ethylene glycol are expected to improve [113].
